4. Schema aware processing

There are four ways to enable schema aware processing:

Command line (long): --schema-aware[=boolean]
Command line (short): -a
Java system property: com.xmlcalabash.schema-aware=boolean
XML configuration: <cc:schema-aware>boolean</cc:schema-aware>
Ant task: <calabash schemaAware="Ant boolean"/>

Schema aware processing requires Saxon EE. If schema aware processing is enabled, then PSVIs are passed between steps.
